| Grazing green manures may improve N availability and productivity in integrated crop-livestock systems. We hypothesized that grazing green manures, compared with standard soil incorporation with tillage, would increase autumn soil profile NO3-N concentrations. Experiments were carried out for three years between 2009 and 2011 in Manitoba, Canada. Seven different green manure crops or mixtures were grazed with sheep or left ungrazed. Hairy vetch, pea/oat mix and oats produced the greatest forage biomass in two out of three years. In 2010, sweet clover produced a similar amount (5813 kg ha-1). Soybean and lentil failed to compete with weeds; containing 30 to 73% weed biomass in all years. Utilization by sheep for all crops ranged from 28% to 86% but the... |
